A NOTE ON WATER EXCHANGE UNDER FAST ICE IN LUTZOW-HOLM BAY, ANTARCTICA
Under coastal fast ice in the Ongul Strait near Syowa Station, Antarctica, warmer, more saline, and oxygen-poorer water appears in mid-depth and deep layers from winter to spring every year. This water is explained as a result of mixing between Circumpolar Deep Water (CDW) and Winter Water (WW). Thi...

Summary: | Under coastal fast ice in the Ongul Strait near Syowa Station, Antarctica, warmer, more saline, and oxygen-poorer water appears in mid-depth and deep layers from winter to spring every year. This water is explained as a result of mixing between Circumpolar Deep Water (CDW) and Winter Water (WW). This water becomes more like CDW and more homogenized with time from winter to spring, and in December a mixing ratio of 1 : 3-1 : 4 for CDW to WW is required to explain the properties of the homogenized water. It is inferred that the CDW comes along the glacial troughs. Transport of CDW results in a significant amount of heat supply into the water under fast ice. |
